In the coated sand production areas should be strengthened following two aspects: (1) hair coated sand pollution, mainly from the following aspects: ① to reduce the amount of resin and curing temperature; ② coated sand to improve the overall performance of coated sand renewable suppliers, especially high temperature performance; study pollution phenolic resin substitutes ③ strengthened;. (2) coated sand to improve the regenerative capacity of thermal regeneration of the basic principle is to use the old sand boiling thermal pretreatment and regeneration furnace equipment, the first of the old sand crushing and magnetic separation vibration, then fired in boiling regenerative furnace, sand and then through the insulation, cooling, screening can be reused. After recycling the regenerated sand thermal performance up: loss on ignition (mass fraction) <0.3%; particle concentration ratio (mass fraction) 80-90%; gas evolution <3mL / g. In order to ensure the quality of coated sand coated sand core production line regeneration, we must first make sure that the quality of coated sand coated sand regeneration, various performance indicators coated sand must meet production requirements, the test method can be found in the machinery industry standards (JB /T8583.1997 coated sand casting).
